NWN-S series Full- Stainless Steel Closed Type Cooling Tower
The NWN-S series cooling tower is a refined version of the NWN series counterflow closed cooling tower, featuring an enhanced anti-corrosion stainless steel frame structure for improved stability and extended service life;water saving and energy saving, high efficient and environmental frendly.
High-Efficiency Counter Flow Closed Circuit System
Operation
The fluid medium requiring cooling flows through the efficient serpentine coil heat exchanger, while the external spray system continuously moistens the coil surface to facilitate cooling. This allows for the exchange of heat between the cooled medium and the spray water through a partition wall heat exchanger, creating a closed loop for effective cooling. Simultaneously, low-temperature dry air enters the tower in opposition to the spray water, with forced convection from a fan enabling counter-current heat exchange. Once fully exchanging heat, high-temperature saturated air is discharged outside of the tower, effectively reducing overall heat and lowering fluid medium temperature.
Main Parts
▷ The stainless steel frame structure and shell possess exceptional anti-corrosion properties, robust heat resistance, and an exquisite appearance. The structural panels are secured with high-quality 304 stainless steel bolts.
▷ The aluminum alloy axial flow fan is equipped with an explosion-proof motor, ensuring stable and efficient operation. The motor boasts a protection grade of IP55 and an insulation grade of F, providing enhanced safety and reliability.
▷ Stainless steel coils exhibit superior heat exchange efficiency, enhanced corrosion resistance, light weight, prolonged equipment lifespan, and are environmentally sustainable due to their recyclability.
▷ The exclusive drift eliminator designed for counter flow closed cooling towers is adept at efficiently extracting airborne water droplets, boasting minimal wind resistance and an impressive capture rate of 99.99%, thus guaranteeing optimal heat transfer performance.
▷ The air inlet grille is easily detachable, featuring a special 3D three-dimensional 45-degree ventilation channel design that enhances structural strength and wind load resistance. It also boasts anti-corrosion and anti-ultraviolet properties, reduces noise, and requires no maintenance.
